Varicocele and fertility: When Treatment May Be Discussed

A varicocele is a group of enlarged veins in the scrotum, the sac around the testicles. Many people have one without symptoms or fertility problems. Finding a varicocele therefore starts a discussion about its relevance; it does not automatically mean you need a procedure.

Confirm what was found

A clinician can often detect a varicocele on examination, particularly while you are standing. Ultrasound may help in some circumstances. A varicocele seen only on a scan and not felt on examination is described as subclinical and is not usually a reason for fertility treatment.

Tell the clinician about discomfort, changes you have noticed and previous semen results. The male fertility assessment guide explains how these details fit together. Do not assume that any new lump or swelling is the same as a previously diagnosed varicocele.

Ask whether treatment addresses your situation

Treatment may be discussed when a varicocele is detected clinically and semen results are abnormal in someone having difficulty conceiving. Pain can be a separate reason to consider care. Both partners’ fertility circumstances matter when deciding whether a procedure is likely to help the overall plan.

Research suggests a pregnancy benefit for selected people with a clinical varicocele and abnormal semen findings, but evidence about live birth is more limited. A better semen result is not a guarantee of a baby. Ask how the evidence applies if you are already considering assisted conception, rather than assuming the same benefit in every setting.

Compare the options and the follow up

Surgery closes the affected veins while preserving other important structures. Embolisation uses a catheter and materials such as coils to block the problem veins under imaging guidance. Suitability depends on the clinical findings and the expertise available.

Ask about risks, recovery, the possibility that the varicocele persists or returns, and when semen testing would be reviewed. Procedure risks can include bleeding or infection, with other risks depending on the technique. Discuss what you would do if symptoms or fertility did not improve.

The low sperm count guide describes why treatment choices are based on more than one finding. Observation or another fertility approach may also be part of the discussion.

Do not wait with concerning symptoms

Arrange an assessment for a new lump, swelling, a change in a testicle or persistent discomfort. Sudden severe testicular pain needs emergency care. Testicular pain with nausea, vomiting or abdominal pain, or pain lasting more than an hour or continuing at rest, also needs immediate assessment. A known varicocele should not be used to explain away these symptoms.
